Identifying genes that influence clinical course and susceptibility in multiple sclerosis. This project aims to identify the genetic basis of multiple sclerosis (MS), the most common neurologic disease in young Australian adults. MS urgently needs research to identify predisposition, aid early diagnosis and provide bona fide molecular targets for new therapies. This will benefit people with MS and those susceptible to it. Crucial new knowledge identified will benefit other major areas of MS rese ....Identifying genes that influence clinical course and susceptibility in multiple sclerosis. This project aims to identify the genetic basis of multiple sclerosis (MS), the most common neurologic disease in young Australian adults. MS urgently needs research to identify predisposition, aid early diagnosis and provide bona fide molecular targets for new therapies. This will benefit people with MS and those susceptible to it. Crucial new knowledge identified will benefit other major areas of MS research including epidemiology, immunology and neurobiology. Collaboration of 8 major Australian institutions is also important for this project and future studies. The team will have access to a new national MS GeneBank (platform) with samples from 2240 patients that should generate findings important to world-wide MS genetic knowledge.Read moreRead less
The role of turgor in hyphal extension of the Ascomycete Neurospora crassa. Cellular expansion is an absolute necessity during the growth and development of plants and fungi. This process relies heavily upon the accumulation of inorganic ions. Osmotically driven water influx then creates the hydrostatic pressure that underlies the increase in cell volume. Cellular expansion is normally asymmetric and localised in one small region, such as hyphal tip. How does the cell maintain the turgor that dr ....The role of turgor in hyphal extension of the Ascomycete Neurospora crassa. Cellular expansion is an absolute necessity during the growth and development of plants and fungi. This process relies heavily upon the accumulation of inorganic ions. Osmotically driven water influx then creates the hydrostatic pressure that underlies the increase in cell volume. Cellular expansion is normally asymmetric and localised in one small region, such as hyphal tip. How does the cell maintain the turgor that drives expansion? How is expansion controlled spatially? These questions will be addressed in this project by comprehensive study of ion transport processes in a model organism, Neurospora crassa, using osmotic sensitive and transport mutants.Read moreRead less
Modelling and control of mosquito-borne diseases in Darwin using long-term monitoring. Management of mosquito populations is a high public health priority because these insects can spread diseases such as malaria, dengue, Ross River virus, Barmah Forest virus, Murray Valley encephalitis, Japanese encephalitis and Kunjin/West Nile virus. Our research into the effectiveness of mosquito control programs in Darwin is of immediate national relevance and priority given the need to Safeguard Australia ....Modelling and control of mosquito-borne diseases in Darwin using long-term monitoring. Management of mosquito populations is a high public health priority because these insects can spread diseases such as malaria, dengue, Ross River virus, Barmah Forest virus, Murray Valley encephalitis, Japanese encephalitis and Kunjin/West Nile virus. Our research into the effectiveness of mosquito control programs in Darwin is of immediate national relevance and priority given the need to Safeguard Australia from invasive diseases. There is an urgency to undertake our research because global environmental change and increasing movements of people (particularly military personnel) from overseas regions where these diseases are endemic is increasing the vulnerability of northern Australia to the (re)establishment of mosquito borne diseases.Read moreRead less
Visualising neuron-glia interactions in the injured central nervous system. The adult brain and spinal cord recovery poorly from injury. Attempts to overcome this problem include methods to promote the intrinsic regenerative capacity of injured neurons, and modulating the inhibitory extracellular environment to become permissive to regeneration. The goal of this project is to investigate an endogenous regenerative mechanism in the injured brain.

Attempts to overcome this problem include methods to promote the intrinsic regenerative capacity of injured neurons, and modulating the inhibitory extracellular environment to become permissive to regeneration. The goal of this project is to investigate an endogenous regenerative mechanism in the injured brain. This project will use the latest, cutting-edge microscopy techniques to visualise whether the endogenous astrocyte protein metallothionein can promote regeneration in the injured nervous system of living zebrafish. The successful outcomes of this project will provide significant insight into understanding how the brain responds to injury.Read moreRead less
Predicting the diagnostic performance of individuals and organisations. Predicting the diagnostic performance of individuals and organisations.

Predicting the diagnostic performance of individuals and organisations. This project aims to address diagnostic error in advanced technology systems, by providing a mechanism to assess and improve individual diagnosticians’ performance. Organisations that rely on their employees’ diagnostic skills rarely assess them once the operators become qualified, so there is no basis for interventions that might prevent diagnostic errors affecting thousands. This research tests a new method of assessing diagnostic skills based on how skilled operators respond to cues. This project will test how employees’ diagnostic skills change and whether this change corresponds to measures of organisational performance. This research is expected to provide organisations with a tool to pre-empt diagnostic errors that could minimise costs to the economy.Read moreRead less
Ring constructions and algorithms for enhancing performance of BCH codes. BCH codes form a major class of codes used in modern communication systems.

Investigating the molecular function of alpha-Haemoglobin stabilising protein. The research described in this proposal will provide new insights into haemoglobin regulation and redox chemistry in erythrocytes. Deregulation of these processes gives rise to a number of debilitating diseases, including varieties of anaemia and thalassaemia-in Australia it is estimated that 3% of the population could be carriers of b-thalassaemia mutations.

The research described in this proposal will provide new insights into haemoglobin regulation and redox chemistry in erythrocytes. Deregulation of these processes gives rise to a number of debilitating diseases, including varieties of anaemia and thalassaemia-in Australia it is estimated that 3% of the population could be carriers of b-thalassaemia mutations. Given the contribution of free aHb to the pathology of b-thalassaemia, understanding the specific aHb-binding factor, AHSP is a goal of national significance. In the long term, manipulation of AHSP function through gene therapy may have a direct role in the treatment of thalassaemia.Read moreRead less
